The fundamental nature of networking is changing, especially in enterprise data centers. With new, integrated applications deployed against large scale, highly virtualized server farms, server-to-server center communications are demanding a completely new level of intra-data-center performance. Traditional three-tier networks - designed to support data-center-in/data-center-out traffic and built using legacy, poor-performing redundancy protocols - can't deliver the server-to-server capacity required for these types of workloads. One innovation is Intelligent Resilient Framework (IRF), a technology that ...

Your network is time stamping files, email, transactions, etc., while your server logs are recording the transactions in case you need that information. Fundamental to all of this is the belief that the time is correct. This paper describes why network time synchronization is critically important.

The original framers of ARPAnet did not foresee the growth of what is now known as the Internet, or that the IPv4 address structure would fall short of the addresses needed, or all the new devices that would need IP addressing. Consequently, the IPv4 addresses are being exhausted. IPv6 satisfies the increasingly complex requirements of hierarchical addressing that IPv4 does not provide. One key benefit is that IPv6 can re-create end-to-end communications without the need ...

Multiprotocol Label Switching (MPLS) began as a way for routers to short-cut the time-consuming process of treating each packet independently, looking up the target IP address each time and in every router along the path. MPLS streamlines the packet forwarding process by introducing a label, assigned by the ingress edge router, into the packet. The beauty of MPLS is that the label itself has no meaning other than what the software gives it. Therefore, the ...

Mobile networking technology is progressing to support the requirements of today's new class of Internet users who roam about with sophisticated mobile computers and digital wireless data communication devices. Normal and fast handover procedures for Wireless LAN are introduced and compared each other. An overall procedure is proposed that manages the layer 2 (L2: link layer) and layer 3 (L3: network layer) handovers simultaneously. Two types of the L2 triggers in Wireless LAN system are introduced: pre-handover-trigger ...

IPv6 is a network layer Internet protocol (IP) standard used by electronic devices to exchange data across a packet-switched internetwork. The Internet is evolving rapidly towards the use of mobile devices that must be able to communicate with other mobile and stationary devices. The need for more Internet addresses for the many devices that will be Internet-enabled will, at some point in time, exceed the capability of IPv4. IPv6 can provide enough IP addresses that ...

Multicast and mobility over satellite using IPv6 is a collaborative project, funded by CNES (French National Space Agency), led by 6WIND (private French leader and innovator of embedded IP networking software), Astrium (a world leader in the design and manufacture of satellites) and LSIIT (Strasbourg University IPv6 research team). In the context of ""Anywhere, anytime Internet access"" its objective is to identify applicative scenarios that could best benefit from multicast and mobility features over satellite. ...
